The Atomic DT 2.0 multi-activity jacket is a typically efficient Montane design that puts function above fashion. At 326g (size M) it is very a light and packable , making it ideal for mixed activities. The fabric is Entrant, which is a well-proven waterproof and breathable fabric. The design is relatively close and short but it still maintains excellent freedom of movement. There are two chest pockets, and these can be easily accessed while wearing a rucksack. They are mesh-lined too for weight reduction and extra venting. The front zip gets an internal stormflap that is Velcroed in place, which – while not as watertight as an external stormflap – is better than nothing. The hood is particularly impressive as it can be rolled to the collar for biking and climbing. On the head its wired peak, fit and movement are all superb. This is a great all-rounder and when the price is considered it is an absolute bargain. But an even higher price would bring improved fabric performance. I’d also like to see more reflective piping for night riding. For running there are lighter jackets of course. But otherwise not a lot wrong with the Montane Atomic DT 2.0 at this price.
